IPAD Coverage in the Maritimes

I live in Ontario and use my IPAD 1 on the Rogers 3G network. Planning on a summer road trip down through Quebec/NewBrunswick/Nova Scotia and would like to know if there is Rogers coverage via 3G for the trip. Thanks for any info, I realize that I can use WI-FI when stopped at hotels etc but would like access when the wifes driving for maps; tourist locations etc.
